PENCIL.

To all lwhom t may concern.'

Be 1t known that I, WILLIAM M. HICKS,

' a citizen of the United States, residing at Cranford, in the county ofUnion and State of New Jersey, have invented certain new and usefulImprovements in Pencils, of u hich the following is a specification.

My present invention pertains to animproved pencil, and the objectsthereof are as follows:

First, to produce a pencil in which a relatively small lead may beemployed which does away with the necessity of resharpening the sameeven though the protruding portion of the lead be broken off.

Second, to provide an impeller for the lead which has a relatively slowmovement-and by reason of which waste of lead is avoided.

Third, to provide means whereby the lead is supported by the point, andthis by a tub ing which is preferably made of the same material as thepencil case, as for instance, silver', thus avoiding corrosion of thetube and a consequent impedance of the feeding of the load.

Fourth, the provision of a holder under the barrel cap for a rubbereraser.

Fifth, to so construct the barrel and the impelling mechanism for thelead that a large magazine or holder will be provided for the leadswhich is substantially co-extensive of the length of the pencil, andwhich magazine is normally closed by the eraserholder just mentioned.

The pencil is shown in the annexed drawings, wherein:

Figure 1 is a longitudinal sectional view of the structure, the cap orcover for the eraser being in place;

Fig. 2 is a similar View of the barrel and the interiorly-threadedtubular member which co-acts with the lead-impeller, the eraser-holderbeing shown as unscrewed from the barrel proper, and the cap for theeraser being likewise omitted;

Fig. 3 is a longitudinal sectional view of the impeller and its guidingtube, together with the point portion of the encil;

Fig. 4 is a side elevation o the impeller guiding-tube and the pencilpoint;

Fig. 5 is a perspectiveview of the leadimpeller;

Fig. 6 is a transverse sectional View taken Specification of LettersPatent.

Application filed August 23, 191.7. Serial No. 187,819.

on the line VI-VI of Fig. 1 and upon an enlarged scale; and

cross bar t (see more particularly Figs. 1V

and 7), the ends of which bar are 'soldered to the interior of thebarrel l. As will be seen upon reference to Fig. 7, the bar 4 is narrow,and spaces 5 are left upon each side of the bar between it and the innerwalls of the barrel.l Said tubular member 3 extends through the bar andprojccts'slightly be-- yond the end 4of the barrel l, forming a threadedprojection 6 to which is removably secured a tubular section 7, in theinner end of which is secured a threaded collar o-r sleeve 8 adapted tobe screwed down upon the projection G. The, outer end of thle member Gmay be closed by a disk 6a.

The member 7 and its attached collar 8 form a closure for the openings 5when the parts ai'e screwed together, and likewise pro vide a receptacleor holder for an eraser 9. Said member 7 is of a diameter slightly lessthan that of the barrel l, and a cap-piece 10 is adapted to be slippedover this member and the eraser carried thereby, the lower or marginalvend of said cap 10 forming a flush joint with the end of the barrel whenthe parts are brought to the position which they normally occupy, as inFig. l.

Mounted within the tubular member 2 and extending throughout the lengththereof is a split tube or guiding element 1l, the tube being providedwith a collar l2 at its upper end which prevents the guiding elementfrom being withdrawn from the tubular member, but yet` ermits relativerotation of the element wit reference to said member. This tube 11 isadapted vto receive the lead-impeller comprising a rod 13 adapted tomake a close fit with the interior of the tube, and a cross bar 14 theends of which project outwardly through the slots in said tube 11, anden age the threads formed upon the interior o the tube 2. The lower oroutermost end of the tube 11 is not split,

and such unsplit portion is sweated or other,-

f wise secured to a bushing 15, the lower end t leads. Said leads may bereadily introduced into'the magazine through the openings 5 when theeraser-holder 7 is unscrewed from the threaded projecting element 6.

As above noted, it is designed to use relatively small leads, themagazine being capable of holdin a large number of said leads ofsubstantia ly the full length of the barrel. The leads are omitted fromthe drawing in so far as the magazine is concerned, but a short sectionof lead denoted by 18 is indicated in Figs. 1, 3 and 4.

The element 16, the outer end of which is drawn down or so formed as todirectly support `the lead, the barrel 1, the tube 3 and its extension6, the eraser-holder 7, the cap` piece 10, and the cross bar 4 will allpreferably be formed of a precious or superior metal, as silver, so thatthe pencil will not coi-rode. This is of special advantage in theelement 16 for the reason that it facilitates the feeding out of thelead under the action of the impeller even though the lead be small, andthis without breaking the lead. Where it is attempted to use a smalllead fed through a tube which is formed of a metal which will corrode,perspiration from The y the hands of the user will frequently cause suchcorrosionas will impede the proper lfeeding of the lead or withoutexerting such force upon the lead where it is small, as to cause it tobe broken or ruptured.

The action of the impeller is seemingly clear, as it is of the usualtype. By holding the barrel and rotating the point 16 the impeller maybe caused to move forward or backward according to the direction of ro,-tation. The thread formed upon the interior of the tubular member 2 isof very slow pitch, so that the lead Will be protruded but a shortdistance upon the complete revolution of the barrel with reference tothe point 16.

Having thus described my invention what I claimisz- In a pencil, thecombination of a barrel;

a pencil point relatively rotatable thereto,'

said point making a close it with the outer end of the barrel; a diskcarried by the point 'and closing the lower end of the barrel; alead-impelling mechanism mounted within the barrel and spaced from theinner walls thereof; a tubular member adapted to support said impellingmechanism at its upper end, said tubular member extending outwardlybeyond the end of the barrel and be-l ing exteriorly threaded; a crossbar holding v said tubular member in place a tubular eraser-holderhaving a threaded member adapted to be screwed upon the threadedextension of the tubular member aforesaid; and a cap-piece fitting oversaid eraser-supporting member and making a close lit with the barrel.

In testimony whereof I have signed myv name to this specication.

WILLIAM M. HICKS.
